Template:Schoute permutation/python example

examples with degree 4 (Python code)

This code is part of a Python library called discrete helpers, which is not yet published.

import numpy as np

from discretehelpers.a import int_to_perm


perm_matrix = np.zeros([24, 4], dtype=int)
schoute_matrix = np.zeros([24, 16], dtype=int)

for i in range(24):
    perm_object = int_to_perm(i)

    perm_matrix[i, :] = perm_object.sequence(4)
    schoute_matrix[i, :] = perm_object.schoute_perm.sequence(16)
